Why do I hear the sounds but my wife is oblivious? Then I have to imitate the sound. Then the sound goes away. Then it comes back so I head to the shop. Then the sound goes away. Then the service manager doesn’t hear a thing but “We’ll look into it, you still at this number?”

That happened with me, too. The car was making bad noises squeezes but the mechanics could never seem to hear it. Eventually they found out what it was and I got it fixed shortly before it could have been catastrophic.

That’s supposed to be the piston and connecting rod flying upwards out of the engine through the hood, indicating a massive failure of the connecting rod (or crankshaft)…. in reality, it’s rather unlikely in a typical automotive engine, as the piston would also have to go through the intake manifold- but that can easily happen in a radial engine where the cylinder heads are much thinner finned aluminum castings.
